Definitions

  • the invention relates generally to an enhanced performance connector and in particular to a telecommunications plug having internal shielding to reduce crosstalk. Improvements in telecommunications systems have resulted in the ability to transmit voice and/or data signals along transmission lines at increasingly higher frequencies.
  • Several industry standards that specify multiple performance levels of twisted-pair cabling components have been established.
  • the primary references considered by many to be the international benchmarks for commercially based telecommunications components and installations, are standards ANSI/TIA/EIA-568-A (/568) Commercial Building Telecommunications Cabling Standard and 150/IEC 11801 (/11801), generic cabling for customer premises. For example, Category 3, 4 and 5 cable and connecting hardware are specified in both /568 and /11801, as well as other national and regional specifications.
  • transmission requirements for Category 3 components are specified up to 16 MHZ.
  • Transmission requirements for Category 4 components are specified up to 20 MHZ.
  • Transmission requirements for Category 5 components are specified up to 100 MHZ.
  • New standards are being developed continuously and currently it is expected that future standards will require transmission requirements of at least 600 MHZ.
  • FIG. 2 is a perspective view of the housing 502. Ridges 518 angle downwards towards the load bar and then proceed parallel to the wire receiving channels 510 in load bar 504. The angled opening in housing 502 facilitates insertion of the load bar 504 into housing 502.
  • the load bar 504 will be loaded in the following way. First, the cable jacket will be stripped off approximately 1.5 inches from the end. Next, pairs Br and Gr will be swapped in position as shown in FIG. 5B . To do this, pair Gr will cross between pair Br and pair Bl. This will create a separation between pair Br and the split pair Bl. Pair Bl is referred to as the split pair because it is spread over an intermediate pair in conventional wiring standards. As shown in FIG. 6 , pair Br is positioned between the conductors of the split pair Bl. The tip and ring wires of the Bl pair will be untwisted up to a maximum of 0.5 inches from the cable jacket, such that the wires in the pair are oriented correctly.
  • the pairs that are kept together, Or, Br and Gr are positioned in the first plane of wire receiving channels 510.
  • the split pair Bl that straddles another pair Br, in accordance with conventional wiring standards, is placed in the second plane of wire receiving channels 512.
  • the split pair Bl usually contributes greatly to near end crosstalk (NEXT). By positioning this pair in a second plane defined by wire receiving channels 512, separate from the first plane defined by wire receiving channels 510, the crosstalk generated by the split pair is reduced.
  • FIG. 12 is a side view of the plug insert 700 mounted in housing 800.
  • the shield wall 716 has a top surface 730 which complements or follows the inside top surface 814 of housing 800.
  • Shield wall 714 is similarly formed. This helps contain wires in the shielded areas 706, 708 and 710.
  • FIG. 15 is a perspective view of an alternative isolator 752.
  • Isolator 752 is similar to isolator 702 but is separate from load bar 704.
  • Isolator 752 includes three shielded areas 706, 708 and 710 on one side of the isolator 702.
  • a fourth shielded area 712 is provided on the other side of the isolator 752 similar to that shown in FIG. 8 .
  • Shielded areas 706, 708 and 710 are separated by shield walls 714 and 716 that extend away from the shielded areas parallel to the longitudinal axis of the pairs of wires in each shielded area 706, 708 and 710.
  • FIGS. 22-24 are views of an alternate isolator 1000 which provides 360 degree shielding to multiple pairs.
  • the isolator 1000 is conductive and may be from plastic which is then metallized, a conductive polymer or metal.
  • the isolator 1000 includes a body 1002 having a plurality of enclosed channels 1004 formed through the body 1002. Each channel 1004 receives a pair of wires to isolate the pairs from each other. The enclosed channels 1004 completely surround wire pairs and provide 360 degree shielding.
  • Also formed in the body 1002 is a groove 1006 which receives a wire pair. The groove 1006 does not provide 360 degree shielding but surrounds approximately 180 degrees of the wire pair.
  • FIG. 28 is a partial cross-sectional view of a plug having an overmolded boot 1300.
  • the wires enter the plug housing and are positioned in an internal cavity 507 in the housing 502.
  • the material used to overmold the boot 1300 enters the interior cavity 507 of the housing 502 and surrounds the wires.
  • the load bar may be configured to prevent the overmold material from reaching the portion of the wires that receive IDC's.
  • first channel 1404 and second channel 1406 are tapered from a first end 1420 to a second end 1422 of body 1402.
  • member 1408 has a larger surface area at first end 1420 than at second end 1422.
  • Body 1402 may be molded from a single piece of plastic, conductive polymer, or metal.
  • the isolator 1400 is made from a sheet of metal which rolled to define channels 1404 and 1406.
  • first channel 1404 has a notch 1430 removed from a portion of an end 1432 of first channel 1404.
  • Second channel 1406 may also have a notch 1434 removed from a portion of an end 1436 of second channel 1406.
  • member 1408 may also have a notch 1438 removed from a portion of first end 1420 of member 1408.
